While Luo Youdu was playing with Chou Chou, news came from outside the palace that Dr. Chu Yan, a doctor of calendar calculation, was asking for an audience.
Luo Youdu thought to himself: "It came so fast!"
Then he said: "Let him wait in Wende Hall."
After leaving Chou Chou to Fu Qing'er, Luo Youdu strolled to Wende Hall.
Chu Yan was tied up in the Wende Hall, feeling a little uncomfortable and uneasy in his heart. He secretly looked around, seeing that the Wende Hall was slightly dilapidated, he sighed in his heart: "Your Majesty is a truly benevolent Lord!"
This Wende Hall was a side hall where Luo Youdu used to work and take breaks. Generally, only highly valued core officials were qualified to enter here for interviews.
Chu Yan has been working as a doctor of calendar calculation in Bianjing for ten years. He has always been unknown and is convinced that he has never met Luo Youdu. It is inevitable that he will feel a little uncomfortable when he is suddenly treated with such courtesy.
The sound of footsteps sounded, and Chu Yan was so frightened that he did not dare to move rashly. He lowered his head and bowed: "Your Majesty, Chu Yan, pays homage to you!"
"No gift!"
Luo Youdu pointed to the mat beside him and said, "Dr. Chu, please take a seat."
Chu Yan knelt down on the table respectfully, very reserved.
Seeing this, Luo Youdu smiled and said: "This is the Hall of Wende, there is no need to be too nervous."
Chu Yan composed himself and said: "I am here for the mathematics compiled by Your Majesty."
Luo Youdu smiled and said: "What does Dr. Chu think of mathematics?"
Chu Yan exclaimed: "I am astonished! I studied all night and incorporated Chinese numerals into "Zhou Bi Suan Jing" and "Nine Chapters of Arithmetic", and found that the original calculation method of hundreds of words was calculated using Chinese numerals.
It’s just a short calculation, it’s incredible.”
He finally added: "Isn't your Majesty a god?"
Later generations may think Arabic numerals are very simple, but these simple ten numbers are the result of countless mathematicians spending hundreds or even thousands of years studying evolution.
China already has a solid digital system, which is complex and abstruse and daunting.
This is also why spells cannot be spread over a wide range.
It's so professional that most people can't accept it.
Even Luo Youdu, when faced with the three-dimensional equations in "Ji Gu Suan Jing", has a head and two people.
Randomly excerpted a sentence: "If you build an embankment, the west head will be six feet, eight feet and two inches wide at the bottom, and the east head will be six feet and two inches wide at the bottom. The east head will be three feet taller and one foot taller than the west head, and the upper width will be much wider."
The east end is four feet nine inches high, and the main area is more than the east end, which is four hundred seventy-six feet nine inches high..."
All calculation methods and problem-solving algorithms are memorized word by word.
China's mathematics is ahead of the world, but its counting methods lag behind for more than a thousand years.
It was not until the Guangxu period of the Qing Dynasty that Arabic numerals were accepted and used in China.
I have to admire this, my ancestors are awesome.
Using a backward counting method, it has led the times in this field for thousands of years.
The popularization of Arabic numerals will make it easier for people all over the world to count, and will also make the history of Chinese mathematics make further progress.
This mathematical progress can promote the progress of physical chemistry.
Luo Youdu was a businessman in his previous life and knew little about mathematics, physics and chemistry.
As an emperor, he cannot devote himself to studying these things. What he can do is mark the passing lanes and let the people below study them to stimulate the progress of the times.
Arabic numerals are the overtaking lane in mathematics.
Luo Youdu looked at Chu Yan who was amazed and said with a smile: "In the doctor's opinion, can this set of numbers be incorporated into the Ten Books of Calculation?"
Chu Yan was a great mathematician of this era. He had the most profound attainments in the four arithmetic classics "Nine Chapters", "Ji Gu", "Zhu Shu" and "Haidao".
He had an apprentice named Jia Xian. Their master and apprentice broke the embarrassing situation in which martial arts had stagnated since Wang Xiaotong in the early Tang Dynasty.
Chu Yan muttered: "I think it is feasible, but it needs to be tested."
"It's okay!" Luo Youdu said: "You can't rush this, you can take your time. I will name the simple numbers after mathematics and use them all over the world to facilitate people's daily calculations. The doctor's task is to compare Chinese numerals with "Ten Books on Calculation"
"Combined with it, we re-edited the Ten Books of Suan Jing in a simpler way."
"If the doctor wants people, I will give them to you. If you need money, I will support you. In short, Chinese numerals are not only a tool to facilitate people's lives, but also the beginning of the revolution in magic. I want to promote magic, and the doctor is the leader."
Chu Yan's blood boiled when he heard it, and his eyes sparkled.
Luo Youdu showed a mysterious smile. After the "Ten Books of Calculation" were compiled, Chu Yan's use of Chinese numerals must have reached a certain level. He also mentioned a few general directions for him to study. I didn't talk about the distant ones and let Shushu go together.
, it shouldn’t be difficult to move forward three to five hundred years.
Luo Youdu specially met with Chu Yan in Wende Hall today, and also gave a message to the outside world that Chu Yan had a very high status in his heart.
As the new year was approaching, Luo Youdu met Zhang Jin again after a month and a half.
It is also the Hall of Wende, but compared to Chu Yan, it is more formal.
Zhang Jin was much more calm and respectfully presented his results of the past month and a half.
Luo Youdu looked at it carefully: Jiao Jixun, the governor of the Zhangwu Army, had more than twenty adopted sons, who were all in key positions in the Zhangwu Army.
Zhongwu Jiedu envoy Zhang Duo believed in Buddhism and built Enci Temple in Xuzhou to pray for his mother. He recruited civilian laborers to build it. In order to meet the construction deadline, he whipped and insulted the civilian laborers, causing two people to become disabled. After the completion of the construction,
No wages were paid on the grounds of conscription of labor.
Hou Tong, the loyal and upright envoy of Jiedushi, did not do any great evil, but he liked cockfighting. If his subordinates made mistakes, no matter how big or small they were, they would be forgiven as long as they offered a famous chicken. Under his protection, his subordinates were able to do whatever they wanted and disturb the people.
Harming people has become the norm.
Gong Shu, the military governor of Zhen'an, was gifted a thousand acres of fertile land for his service to Gaoping. In order to irrigate his own fields, he forcibly intercepted the river and changed the river course, causing tens of thousands of fields downstream to be affected. This has lasted more than eight years...
Luo Youdu looked at these random acts, and he was not particularly angry. He just said, "I will summon them to Beijing. You can do it on the road and take them directly to the prison!"
At the same time, Luo Youdu ordered Gao Huaide and Shi Shouxin to make preparations to move south to Suqian and west to Songzhou and Xuzhou to be ready.
In just two days, six Jiedu envoys were captured by Wude envoys one after another.
In an instant, the court was shocked.
None of the civil and military officials could have imagined that the benevolent Lord, who was usually friendly and smiling with them, would be so ruthless and take down six Jiedu envoys in one go.
The methods were as radical and ruthless as Guo Rong's, after the Battle of Gaoping, where he chopped off more than 70 heads in one go.
Regular meetings.
Civil servants and military generals were on both sides.
The atmosphere was solemn.
Luo Youdu loved to laugh, and the first sentence in the historian's record of his daily life was, "The king is funny, gentle and approachable, and is deeply loved by all officials."
Therefore, since Luo Youdu ascended the throne, the atmosphere of court meetings has always been relaxed and comfortable.
All major national affairs were resolved one by one in a cheerful atmosphere.
Compared to Guo Rong's solemnity, civil and military officials liked this new atmosphere more.
However, six people including Jiao Jixun, Zhang Duo, Hou Tong, and Gong Shu were arrested together.
The civil and military officials of the Manchu Dynasty suddenly realized that the benevolent Lord they were loyal to might be more powerful than Guo Rong.
At least there were traces of Guo Rong's anger, but Luo Youdu remained silent and took down the six Jiedushi envoys with great force.
The civil and military officials of the Manchu Dynasty, including several prime ministers, military bosses, and local officials, were not aware of it at all.
Even Jiao Jixun, Zhang Duo, Hou Tong, and Gong Shu themselves only realized they had been tricked the moment they were captured.
After Chai Shouli put Luo Youdu under house arrest in Xiangguo Temple, the six of them were all frightened. While preparing for a desperate fight, they sent people to Bianjing to investigate the situation.
As a result, it seemed that nothing happened to Luo Youdu. He took concubines to fight against the Confucius family, promoted education, and discussed national affairs with civil and military officials in a peaceful manner every day, without any intention of making things worse.
The six people couldn't help but heave a sigh of relief when they saw this, and some even thought of contempt.
Until Takeshi takes it...
Luo Youdu came to his seat and sat down as before. He saw that the atmosphere in the hall was a little different from before, and he understood why.
His character was funny and casual. After becoming the emperor, he did not deliberately make himself miserable in order to maintain his dignity. He still went his own way.
Majesty is never achieved by keeping a straight face.
"See Your Majesty!"
Luo Youdu said: "I love you all." He looked at His Highness's civil and military officials and said: "I think you have already anticipated the content of today's court meeting. Jiao Jixun, Zhang Duo, Hou Tong and Gong Shu are all meritorious officials! Jiao Jixun is here
The Battle of Huainan and the Northern Expedition to Yanyou both had great achievements. But so what? Military merit is not a talisman for his evil deeds, nor is it a reason or excuse for them to harm and oppress the people..."
"I will not be stingy with rewards for those who have made meritorious deeds. But I will not show any mercy to those who are proud of their merits and persecute the people."
His eyes swept across the array of His Highness's generals.
Han Lingkun, Han Tong, Gao Huaide, Pan Mei, and Cao Bin responded calmly, while Shi Shouxin did not dare to look at them, feeling a little guilty.
He sat at the top and said sadly: "After all, he is a meritorious minister, and I don't want to humiliate him with ordinary interrogation methods. I decided to select three people from the military and hold a military trial to convict them of their crimes."
"As for the candidates, we will take General Xiang Xun of Zuowei as the leader, Taifu Li Jun, and Shi Shouxin, the commander in front of the palace, to assist him."
Luo Youduruo gave Shi Shouxin a meaningful look.
This guy's temperament has changed a lot since he followed him.
I only occasionally get confused, mostly due to temper problems and have little impact.
Luo Youdu was just hammering away this time to avoid causing trouble.
Luo Youdu had no intention of discussing this matter with anyone.
From the beginning, he had the intention of killing the chicken to scare the monkeys, and gave them an extra way to let them take it lightly and avoid rebellion.
Although the current Jiedu envoys do not have the strength to rebel, it would still be troublesome if they were pushed to the extreme and jumped over the wall, forcibly recruiting strong men in the city and holding on to the city to defend it.
"Okay, this matter has been decided. If you have something to do, please come to the court. If nothing happens, just retreat from the court!"
He still responded with a smile, but His Highness Wenwu did not dare to respond with the same attitude as before...
